diastereoisomeric methyl 2,4,6-trideoxy-4-trifluoroacetamido- l -hexopyranosides have been synthesized. Coupling of the corresponding 1- O -acetyl-3- O -benzoyl- l - lyxo and 1- O -acetyl-3- O - p -nitrobenzoyl- l - arabino derivatives with daunomycinone in the presence of p -toluensulfonic acid as catalyst afforded two new anthracyclines.
摘要合成了四种非对映异构体甲基2,4,6-叔氧基-4-三氟乙酰氨基-1-己吡喃糖苷。在对甲苯磺酸作为催化剂存在下,相应的1-O-乙酰基-3-O-苯甲酰基-1-lyxo和1-O-乙酰基-3-O-对硝基苯甲酰基-1-阿拉伯糖衍生物与daunomycinone的偶联提供了两个新的蒽环类药物。
